A

The output will clip the signal at the maximum output voltage.

B

The output will amplify the signal without any distortion.

C

The op-amp will shut down to protect itself.

D

The output will produce a negative voltage regardless of the input.

Understanding the Answer

Let's break down why this is correct

An op‑amp cannot exceed the voltages it is powered from. Other options are incorrect because Some think an op‑amp keeps amplifying no matter what; People sometimes imagine the device shuts down to protect itself.

Definition

Op-amps have output limitations due to the voltage range of their power supply. When the output voltage exceeds this range, the op-amp saturates and outputs the maximum or minimum voltage. Saturation can lead to signal clipping near the power supply rails.
